摘　　要：A2/O + MBR工艺为A2/O工艺与MBR工艺的串联组合,利用了MBR膜池代替A2/O工艺中的二沉池,使其具有更小的占地面积和更加优质、稳定的出水水质保障。为了探究传统A2/O工艺及A2/O + MBR工艺在城镇污水处理中的应用效能,在同季节、同时段、进水均匀分配的条件下,比较分析了两种工艺在连续31 d中对污染物的降解效能。结果表明:A2/O + MBR工艺在处理城镇生活污水的效果上优于传统A2/O工艺,且抗冲击负荷能力更强,是更具优势的成熟工艺。A2/O工艺、A2/O + MBR工艺的平均处理成本分别为0.4702元/m3、0.6354元/m3,传统A2/O工艺运行成本比A2/O + MBR工艺低0.1652元/m3,相较之下更具经济性。The A2/O + MBR process is a series combination of A2/O process and MBR process. The MBR membrane tank is used to replace the secondary sedimentation tank in the A2/O process, so that it has a smaller floor area and better quality and stable effluent quality assurance. In order to explore the application efficiency of traditional A2/O process and A2/O + MBR process in urban sewage treatment, the degradation efficiency of pollutants by the two processes in 31 days was compared and analyzed under the condition of uniform distribution of water in the same season and at the same time. The results show that the A2/O + MBR process is superior to the traditional A2/O process in the treatment of urban domestic sewage, and the impact load resistance is stronger, which is a more advantageous mature process. The average treatment costs of theA2/O process and the A2/O + MBR process are 0.4702 yuan/m3 and 0.6354 yuan/m3, respectively. The operating cost of the traditional A2/O process is 0.1652 yuan/m3 lower than that of the A2/O + MBR process, which is more economical.
